History/Motivation
2
“Passenger Bill of Rights” currently under debate as part of FAA Re-AuthorizationLengthy tarmac delays occur almost daily, but the Bill is being motivated/propelled forward by rare, high-impact, and high-visibility events
E.g. Minnesota Rochester flight brought on Sen. Amy Klobuchar as a supporter of the bill
As a result, focus of bill is on “three-hour tarmac rule”
Implications
The Bill will pass …… or it won’t…But either case will likely have the same outcome (virtually no change)
Very few flights fall into the three+ hour categoryMaybe of them would be exceptions to the rule
3
ImplicationsIf flights are forced to turn back, benefit to passengers on impacted flights will be mixed
Some passengers will opt to get off (but may have trouble re-booking if load factors remain high)Some passengers will want to continue on
Even longer delay as flight re-enters departure queueMore likely, flight will be cancelled
4
Going ForwardThe Bill may well disappear from focus, but the problem will notReal opportunities to exist to reduce tarmac delays
Benefit to passengersBenefit to airlinesBenefit to environment
5
Research GoalQuantifying, codifying, and analyzing ground delaysEvaluating cost impacts of different types of delaysIdentifying resources/policies that could reduce delays; assessing their costs (true, opportunity)
6
Example: Assessing Severity of Delay
2009 TAXI OUT TIME >= 180 min
7
Example: Assessing Severity of Delay
566
TAXI OUT TIME (JANUARY 2009 - AUGUST 2009) 8
Example: Importance of Focusing on Geography
Sen. Boxer, when asked about NYC congestion: “That’s not what we’re here to talk about”In June, 172 flights > 3 hours79 of 172 were from LGA, JFK35 were on June 26 (Friday); 25 were on June 9 (Tuesday); 15 were on June 30 (Tuesday)

Research QuestionsHow should delays be categorized?
E.g. Outbound vs inbound; weather (snow vs lightening)
How are delays distributed within these classes?E.g. Frequency, duration
How do we measure the impact/cost of delays?Are all delays of the same length equal?Is the increase in cost linear relative to delay length?
12
Research QuestionsWhat resources could be used to help mitigate different delays? What are the true/opportunity costs of these resources?
Gates?Reserve crews?
What policies might be considered?New taxi queuing policies?Gate sharing under extreme conditions?
13
ConclusionsIn order to fix the problem, we need to understand it (analysis vs. sound bites)Never-ending plug for:
DataInsightsAccess Opportunity to contrast U.S. and European/Asian/Latin American conditions, best practices
